We look at the division of 731574 by 9 
The aim is to understand the frequency of 9 in 731574.

Step 1:
9 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 9

Step 2:
9 goes into 73 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 72 from 73 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 9

Let's proceed to step 3:
When dividing 11 by 9, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Deduct 9 from 11 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 9

Advancing to step 4:
25 divided by 9 is 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 812.0
If we take 18 away from 25, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 9

Step 5:
The number 9 fits into 77 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 8128.0
Subtracting 72 from 77 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 9

Moving on to step 6:
The number 9 fits into 54 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 81286.0
Deduct 54 from 54 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
9 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 81286.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
9 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 81286.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 81286.0, and the remainder is 0.0.
